Default Stalls when first starting, then runs fine

So recently i bought a CBR600 F2 -94 (my first bike)

i have a quite interesting problem with it. when i start it upp in the morning.
Thing is it runs for about 0.5-1km and then just starts dying just like it out of petrol or the line would be turned of.
But it's on and i have a full tank and it doest help even if i would turn on the Reserv.

Then after it dies it wont start for about 10min.
Feels like it's not getting any gas but i cant figure out why

and after the 10min it starts like nothing happened and can run the whole day without issues.

Untill a couple days later when it happens again.
Allways on the first startup in the morning every couple of days.

So hoping someone might have a idea what might be causing this.
Tips would be appreciated

blockage in fuel line, intank-filter, or carbs need to be cleaned. After you start up the bike and the fuel starts to flow through the carbs more, gunk (if there is any) inside the carbs are disturbed and shift around with the fuel, which could be the cause in your case. Good luck. There is a carb cleaning write up on this forum for the f2.

Dont know if you sorted problem..... I reccently had this. i changed the air filter and spark plugs and the problem resolved. also dont leave choke on too long, i figured once it ran for 20 seconds i turned my choke off and let it warm up on tickover... well it worked for me......

Also - check the vent lines hanging off the back of your tank. those should not be clogged or pinched off.

Next time your bike cuts out, open your gas tank cap and see if it will fire back up inside of the normal 10 minutes you say it has to sit.

Check your vacuum lines from the engine to the petcock.

I had that problem once... kinked the breather hose when I put the tank back on. OP... yours is a textbook description of this.
